Echium Plantagineum Salvation Jane - Healing seed oil?
Hi, I am interested in obtaining some of these seeds.
The research I have read is very interesting.
Echium Oil by Ray Sahelian, M.D. Health benefit of echium oil
Echium oil is obtained by refining oil extracted from the seeds of Echium plantagineum. Members of the genus Echium from Macaronesia have a very high amount of gamma-linolenic acid. See oil for a full discussion of various oils. Echium oil use may provide healthy long chained fatty acids.
Composition of echium oil
Echium oil is a vegetable oil rich in omega-6 and omega-3 polyunsaturated fatty acids.
Food Uses of echium oil
Croda Chemicals wants to use its refined echium oil as an ingredient in a range of food products (including milk and yoghurt based drinks, breakfast cereals and nutrition bars) and in food supplements.
Echium oil and blood lipids
It appears that echium oil could be beneficial in reducing certain blood lipids.
Dietary echium oil increases plasma and neutrophil long-chain (n-3) fatty acids and lowers serum triacylglycerols in hypertriglyceridemic humans.
J Nutr. 2004. Surette ME, Edens M, Chilton FH, Tramposch KM. Pilot Therapeutics Incorporated, Charleston, SC
The objective of this study was to investigate the effect of dietary echium oil, a plant oil containing the 18-carbon (n-3) PUFA stearidonic acid, on tissue fatty acid content and serum triacylglycerol concentrations in hypertriglyceridemic humans. Asymptomatic subjects with mild-to-moderate hypertriglyceridemia were enrolled in an open-labeled study. Subjects underwent a 4-wk lead-in period and were then instructed to follow the National Cholesterol Education Program Step 1 diet. Subjects whose serum triacylglycerol concentrations remained between 300 and 450 mg/dL were instructed to consume 15 g of echium oil daily for 4 wk. During the treatment period, serum triacylglycerol concentrations decreased by 21% compared with baseline. There were no significant changes in any other clinical laboratory variables. Concentrations of long-chain (n-3) PUFA, including EPA, increased in plasma and neutrophils when subjects consumed echium oil. In conclusion, dietary plant oils rich in stearidonic acid are metabolized to longer-chain, more unsaturated (n-3) PUFA. These oils appear to possess hypotriglyceridemic properties typically associated with fish oils.
Echium oil reduces plasma lipids and hepatic lipogenic gene expression in apoB100-only LDL receptor knockout mice.
J Nutr Biochem. 2007. Section on Lipid Sciences, Department of Pathology, Wake Forest University School of Medicine, Winston-Salem, NC 27157, USA.
We tested the hypothesis that dietary supplementation with echium oil, which is enriched in stearidonic acid (SDA; 18:4 n-3), will decrease plasma triglyceride (TG) concentrations and result in conversion of SDA to eicosapentaenoic acid (EPA) in the liver. Mildly hypertriglyceridemic mice were fed a basal diet containing 10% calories as palm oil (PO) and 0.2% cholesterol for 4 weeks, after which they were randomly assigned to experimental diets consisting of the basal diet plus supplementation of 10% of calories as PO, echium oil or fish oil (FO) for 8 weeks. The echium oil and FO experimental diets decreased plasma TG and VLDL lipid concentration, and hepatic TG content compared to PO. Echium oil fed mice had plasma and liver lipid EPA enrichment that was greater than PO-fed mice but less than FO-fed mice. In conclusion, echium oil may provide a botanical alternative to fish oil for reduction of plasma TG concentrations.
Echium Oil Research
Occurrence and characterization of oils rich in gamma-linolenic acid Part I: Echium seeds from Macaronesia.
Phytochemistry. 2000 Feb;53(4):451-6. Departamento de Ingenieria Quimica, Universidad de Almeria, Spain
Nineteen species of the genus Echium (Fam. Boraginaceae) collected in Macaronesia were surveyed in a search for new sources of gamma-linolenic acid (GLA, 18:3omega6). High amounts of this acid were found in all of them, ranging from 9% (Echium plantagineum) to 26% (Echium callithyrsum) of total seed fatty acids. The amounts of GLA related to total seed weight were also significant, ranging from 1.7% (Echium sventenii) to 5% (Echium nervosum). In addition, considerable amounts of stearidonic acid (SA, 18:4omega3) were detected, ranging from 3% (Echium auberianum) to 13% (Echium plantagineum) of total fatty acids.

Q. I have just been reading your web page on echium oil and was interested in your comments about "pyrrolizidine alkaloids and their N-oxides." being present in the refined oil. Now, like most members of the Boraginaceae (including borage), echium contains these alkaloids in the plant parts but I wasn't aware that they were present in the oil, and I would anticipate that, even if they were, they would be removed by even a simple refining process. In their Novel Foods application in 2000, Kings wrote: "Pyrrolizidine alkaloids are not lipophillic and, therefore, would not
be expected to be present in any substantial quantity in the oil. Tests carried out on several samples of both Super Refined and unrefined Echium oil shows that levels of Pyrrolizidine Alkaloids were either extremely low ( A. Thanks, we removed the reference to pyrrolizidine alkaloids in the section on composition of echium oil. Is it okay to use your name as the person who let us know about this?
